I haven't given a lot of thought into supporting ICP_OP_ADVERTISE
and ICP_OP_UNADVERTISE for Squid. However, at first look it seems
that it would best be implemented as an entirely new, separate
data structure (hash table, whatever). So I don't think we would
need to allocate future space in any current structures/files.

Also, with 1.2 we have the ability to place variable-sized
meta data in the object swapfiles. For example, URLs now
go here and only MD5's are written to the "swap.state" files.
